AUXILIARY onoss r maine;

Application filed August 18, ietioi'lmijb. {$725,952. j i i Thisinvention relates to a device for changing cross arms.

The chief object of this invention to provide a temporary support for across arm or a temporary cross arm, detachablysupported on a pole towhich the wires supported by the cross arm to be replaced aretemporarily secured or supported during the changing from the originalto the replacing cross arm. v

The chief feature of the invention consists in the particularconstruction of the cross arm supporting base and the detachablemounting therefor upon a pole.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claim:

In the drawings, Fig. 1 is a side elevational view of one form oftemporary cross arm associated with the cross arm support showing thesame applied to a pole, the latter being shown dotted.

Fig. 2 is an enlarged top plan view of the cross arm support and polemounting mechanism, the pole being shown dotted.

Fig. 3 is a front view of a cross arm support and pole clampinglever.

Fig. 4 is a side elevation of the attachment,

including the auxiliary cross arm and showing the same mounted upon apole, the latter being shown in elevation.

In the drawings 10 indlcates apole and 11 a cross arm. Means fortemporarily mount ing the cross arm on a pole includes a supportingportion which is clampingly mounted on said pole. r p

The base portion of the aforesaid supporting means, includes a partiallycylindrical portion 12, which "is provided at its parallel edges withtwo outwardly and oppositely directed wings 13 and 14. Wing 14 isnotched at 15 and said notch or groove is defined by a-pair'ofparallelflanges 16, apertured as at 1 17 to receive a pivot form of a bolt orthe like 18. The wing 13.is suitably apertured as at V 19 and aneye-bolt 20 is supportedthereby and supports one end of a'link chain 21or other flexible clamping construction, Link chain 21'is adapted tohave any one] of its. links associated'with the hook portion 22 of ahook link member 23,;which has; a curved I portion 24=and passes:over'the-pin 18jas a T fulcrum. The other end of the hook 'terminatesin an eye 25 which is pivoted as at 26 upon a lever having thebifurcated ends 27 I 5! which straddle the eye portion 25 and said leverterminates in a-handle portion 28.. -After the handle is tiltedcounterclockwise,

see Fig. 2, and the chain link is associated with the hook portion 22with substantially all of 7 I the slack taken fromthe chain, thenclock-J wise movement of the lever 28 upon the pivot 18 will cause thechain-andpartially cylindrical portion 12, to clampingly engage the Theupper end of the wings 13 and 14 and p the upper edgeof the partiallycylindrical portion 12, terminate in a transverse plate 30 which ispractically divided into two portions v by the partially cylindricalportion. See

Fig. 2. V

Likewise, illustrated in said figure, is an [upstanding wall 31,integral with the plate 30 at its bottom edge and which is tangential tothe projected cylindrical surface of the par- 5 tially cylindricalportion 12. Reinforcing webs 32 insure rigidity of the wallconstruction. The wall is also provided with a suitable number ofopenings 33 and 34. The

cross arm 11 is supported by the wall portion 30 i and in substantiallytangential relation to the pole. See Fig. 4. Herein-the temporary orauxiliary cross arm 11 includes a plurality of hooks 40, arranged inspaced relation and if desired, the cross arm may include pivoted endportions, as at 41, pivoted at 42 and nor-' mally retained in cross armalignedposition' by suitable manually engageable latches 43,

or when released therefrom, said portions 41 may be positioned as shownin the left hand portion of Fig. 1. Infthis position, portion .41andthehooks 40 thereon, are adapted to support a number. of superposedwires, while whenpositioned a'sshown in the right hand of Fig. 1, thecrossarm isarranged to-support five wiresjpositioned in substantiallyhorizontal alignment. V The invention claimed is In a pole attachment,

cuatei'plat'e "conforming arelatively to a portion of the 99 veireumference of the pole, a wing at each end i of said platecoextensive with said ends and disposed substantially in the same planewith'each other, a cross arm attaching wall of appreciable length andintegralwith the upper side of said plate tangential with the latter andsubstantially parallel, with. said wings, webs connecting the upperportions of the wings with the lower edges of the wall,

and a lever operated fiexible'retaining member associated with saidwings =f0r detach ably holding the plate to said pole; the rep 7 l-ationof the plate and cross arm attaching wall being such that saidwall Oranarm car- Y Y riedthereby does not interfere"withioperae "tion ofthelever; 1 j 5 In witnesswhereo f, I have hereunto aflixed j mysignaturei.
